Flash Exposure Bracketing – FEB
Flash Exposure Bracketing (FEB) can be used to automatically change flash
power over a series of photos. The camera will record three images with dierent
exposures – one exposed as per camera calculations, one over-exposed and
another under-exposed. Over and under exposure levels can be set by the user.
FEB is useful in run-and-gun situations as well as when shooting scenes with
different lighting conditions to help ensure a properly exposed photo. It can
also be used for HDR photography. Some cameras have ash exposure storage
Function, see your camera user manual for more details.
1. Hold down the Button for 2 seconds. The FEC icon will displayed
in the top right hand corner of the LCD .

Please note:
- FEB can be used in conjunction with FEC and Flash Exposure Lock (FEL)
- For best result, set the camera drive Mode to single frame, and before the
second and third picture is taken, make sure the ash is fully recycled.
Flash Exposure Lock–FEL
The Juno TTL is compatible with Flash Exposure Lock (FEL) Functionality. FEL can
be used to lock the ash exposure before a photo is taken. See your camera user
manual for further details on using FEL.
High Speed Sync – HSS
In HSS Mode, the camera/flash maximum sync speed can reach the camera’s
maximum shutter speed. This is useful when using Aperture Priority Mode or
to limit ambient light. HSS may vary with dierent camera models - see your
camera user manual for details.

16

5. To re-meter press and hold the OK Button for 2 seconds to re-enter Auto
Metering Mode.
Multi: Stroboscopic Mode
With Multi Stroboscopic Mode a series of rapid ashes will be red. The ash
count, frequency and power of these ashes can be programmed on the Phottix
Juno TTL. Multi Mode is useful for capturing multiple images of a moving
subject in the same photo and other special eects. The frequency of the eect
(in Hz. - number of ashes per second), the total number of ashes and output
levels can be set.

18
To Use:
1. Press “MODE” Button until the ash displays Multi on the top left corner of
the LCD.
2. Press Button to enter Power Adjustment Mode, use the Selection
Dial to adjust the ash power
4. Press Button to cycle through Number of Flashes (X) and frequency
(Hz), and use the Selection Dial to adjust these settings.
Please note:
1. Overheating and damage can result from excessive use of the Multi
Stroboscopic Mode. Do not use more than 20 times in succession.
2. When overheated the ash will automatically increase recycling time until
the ash temperature has decreased.
Stroboscopic Mode and Shutter Speeds
To determine the proper camera shutter speed to be used with various
Stroboscopic Mode variables, use the following formula: Number of flashes /
Frequency = Shutter Speed
Example: 5x (number of ashes) / 10 Hz (Frequency) = .5 second shutter speed.
This is a rough guideline: You may need to increase or decrease the shutter
speed to get the desired result.
